Here, we describe a young man with a 1-year history of right-sided foot drop, which developed following a rapid intentional weight loss of 11 kg over a period of 15 days. This weight loss was preceded by rapid weight gain over 2\u2009days owing to binge eating. Laboratory parameters for systemic\/metabolic disorders were unremarkable. Radiology of the lumbosacral spine was unremarkable. Confounding risk factors included high-intensity training, frequent squatting and stretching. Electrophysiological studies revealed common peroneal (fibular) neuropathy at the fibular head with persistent denervation. This case highlights the diagnostic dilemma between lumbosacral plexopathy\/radiculopathy and common peroneal (fibular) neuropathy. Electrophysiological studies and radiological assessment of the lumbosacral spine suggest that neither CPN nor lumbosacral surgical decompression would be beneficial, emphasising the need for tendon transfer.<\/jats:p>","DOI":"10.1136\/bcr-2024-261757","type":"journal-article","created":{"date-parts":[[2025,1,14]],"date-time":"2025-01-14T07:00:32Z","timestamp":1736838032000},"page":"e261757","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Slimmer\u2019s paralysis in a physical trainer with drastic weight fluctuations"],"prefix":"10.1136","volume":"18","author":[{"given":"Vivek","family":"Shankar","sequence":"first","affiliation":[{"name":"Orthopaedics, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-6425-0141","authenticated-orcid":false,"given":"Nitish Jagdish","family":"Jyoti","sequence":"additional","affiliation":[{"name":"Orthopaedics, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Swayam Prakash","family":"Dash","sequence":"additional","affiliation":[{"name":"Orthopaedics, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Venkatesan","family":"Sampath Kumar","sequence":"additional","affiliation":[{"name":"Orthopaedics, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,1,14]]},"reference":[{"key":"2025082800431002000_18.1.e261757.1","doi-asserted-by":"publisher","DOI":"10.1080\/10790268.2007.11753915"},{"key":"2025082800431002000_18.1.e261757.2","doi-asserted-by":"crossref","first-page":"555","DOI":"10.1159\/000518377","article-title":"Varied Presentation and Importance of MR Neurography of the Common Fibular Nerve in Slimmer\u2019s Paralysis","volume":"13","author":"Shields","year":"2021","journal-title":"Case Rep Neurol"},{"key":"2025082800431002000_18.1.e261757.3","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.47.5.564"},{"key":"2025082800431002000_18.1.e261757.4","doi-asserted-by":"crossref","first-page":"1723","DOI":"10.1212\/WNL.38.11.1723","article-title":"Common peroneal mononeuropathy: a clinical and electrophysiologic study of 116 lesions","volume":"38","author":"Katirji","year":"1988","journal-title":"Neurology (ECronicon)"},{"key":"2025082800431002000_18.1.e261757.5","doi-asserted-by":"crossref","first-page":"632","DOI":"10.1053\/j.jfas.2017.10.035","article-title":"Bilateral Common Peroneal Nerve Entrapment After Excessive Weight Loss: Case Report and Review of the Literature","volume":"57","author":"Margulis","year":"2018","journal-title":"J Foot Ankle Surg"},{"key":"2025082800431002000_18.1.e261757.6","doi-asserted-by":"crossref","first-page":"39","DOI":"10.1249\/JSR.0000000000000931","article-title":"Acute Peroneal Neuropathy and Foot Drop in Two Adolescent Female Athletes with New-Onset Diabetes","volume":"21","author":"Jaeger","year":"2022","journal-title":"Curr Sports Med Rep"},{"key":"2025082800431002000_18.1.e261757.7","doi-asserted-by":"crossref","first-page":"1909","DOI":"10.12998\/wjcc.v9.i8.1909","article-title":"Bilateral common peroneal neuropathy due to rapid and marked weight loss after biliary surgery: A case report","volume":"9","author":"Oh","year":"2021","journal-title":"World J Clin Cases"},{"key":"2025082800431002000_18.1.e261757.8","doi-asserted-by":"publisher","DOI":"10.1007\/s11695-007-9203-2"},{"key":"2025082800431002000_18.1.e261757.9","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1186\/s41983-022-00594-3","article-title":"Slimmer\u2019s palsy following an intermittent fasting diet","volume":"58","author":"Baharin","year":"2022","journal-title":"Egypt J Neurol Psychiatry Neurosurg"},{"key":"2025082800431002000_18.1.e261757.10","first-page":"1330","article-title":"Peroneal palsy after bariatric surgery;
